Title: A starting device for an internal combustion engine
Inventor: GRAYBILL CLINTON LEE
IPC: F02N5/02
Filed: 1963-04-29
Abstract: 986,560. Starting I.C. engines. GRAYBILL INDUSTRIES Inc. April 29, 1963, No. 16813/63. Heading F1K. In an I.C. engine starting device in which an engine cranking clutch element 77 is engaged by a clutch element 16 driven by a spring motor, the spring 35 of which is tensioned by a rotatable and axially displaceable shaft 22, an actuating member 30 is rotated by the spring motor during engine cranking to effect axial displacement of shaft 22 to effect engagement of' clutch element 20 with a clutch element 82 rotatable with clutch element 77 thereby rotating shaft 22 to operate a drive to tension the spring and moving the actuating member 30 to cause axial displacement of the shaft 22 and disengagement of the clutch element 20 from clutch element 82. Spring 35, Fig. 1, is wound by using a winding key to rotate sleeve 57 and gearing 58, 60, 62 to rotate hub 32 which is attached at 40 to one end of the spring, the other end being secured in an opening 42 in a disc 44 which has ratchet elements 45. Detent 88 engages ratchet element 45 to prevent rotation. The winding key is used to rotate detent 88 from engagement with ratchet element 45 so that disc 44, hub 43, cup-shaped member 12 and hollow shaft 30 are driven in clockwise rotation by spring 35 and the resultant cam action of diagonal slots 15 pulls pins 16 in ring 17 downwards into engagement with ratchet teeth 78 in member 77 attached to the engine crankshaft 76 to turn the engine. At the same time hub 43 and spline 47 rotate shaft 30 clockwise which, because of the right-hand screw threads on shaft 30, cause the shaft 30 to move downwards to engage the first clutch member 20 with the second clutch member 82 which, because of lugs 83 engaging the slots 79, is being driven clockwise and this rotation causes teeth 78, assisted by spring 23, to cam pins 16 upwardly out of engagement thus urging the ring in an anti-clockwise direction as the pins move upwards in slots 15. Engine driven clockwise rotation of clutch 20 causes the train of gears 58, 60, 62 to rewind the spring. Clockwise rotation of the hub 32 about the threaded shaft 30 pulls shaft 30 upwardly to disengage clutch members 20 and 82 upon completion of the spring winding operation the disengagement being assisted by spring 52.

Abstract: 1530977 Seals COMMISSARIAT A L'ENERGIE ATOMIQUE and SOUDURE AUTOGENE FRANCAISE 25 April 1977 [28 April 1976] 17031/77 Heading F2B A vacuum sealing device for a bell-shaped vacuum enclosure 1 which can be arranged to surround parts (not shown) to be welded by the beam-welding process, and a vacuum readily applied to facilitate such welding process, comprises an inflatable inner seal 4 concentrically arranged within a solid neoprene annular outer seal 3 having a dihedron 9 for sealing engagement with a flat or cambered bearing surface 5, the sealing compression of the solid seal 3 being limited by a lateral abutment 18. In operation, the enclosure 1 is placed with its outer solid seal 3 resting at 9 on the bearing surface 5 (Fig. 3) and an initial vacuum to half atmosphere is applied via a pump 8 and a valve 16 to the enclosure 1 to solidly seat the enclosure 1 via the abutment 18 against the surface 5 (Fig. 4) at which point the inner seal 4 is inflated by the pump 8 and a valve 17 to further seal the chamber (Fig. 5) to thus enable the evacuation in the enclosure to then be further continued to the required final vacuum, which vacuum would not be possible with the solid seal 3 alone. The arrangement is such that the initial vacuum held by the solid seal 3 prevents the enclosure 1 from lifting when the inflatable seal 4 is pressurized thus avoiding the difficulty of creating a vacuum using an inflatable seal alone, i.e. due to the inflatable seal initially tending to separate the sealing surfaces. The single solid seal 3 may be replaced (Fig. 6, not shown) by a pair of side-by-side solid seals (3a, 3b).

Abstract: 334,586. United Glass Bottle Manufacturers, Ltd., and Moorshead, T. C. June 6, 1929. Blowing; pressing. - Relates to glass-shaping machines of the type in which a pressing-plunger is used for forming a cavity in the molten glass. According to the invention, the pressing-plunger is actuated by gravity in order to keep the pressure on the glass uniform irrespective of any variation in the amount of glass in the mould. The device is shown applied to a machine of the type described in Specification 281,383. The plunger a is supported by, and is free to slide vertically within, a housing c which is raised and lowered bv a fixed cam q as the machine rotates. Weights w are supported by an extension f on the upper end of the plunger, and the number of weights can be varied in order to secure the desired pressure by the plunger on the glass. The plunger is formed with a collar d which rests on a shoulder g at the lower end of the housing c. Thus, when the housing is lowered, the plunger engages the glass in a mould and the housing continues its downward movement and leaves the plunger supported by the glass in the mould. When the housing is raised, the shoulder g engages the collar d and lifts the plunger out of the mould.
